Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide InCell™ Fiber Optic Distributed Antenna System Description The subsystem consists of one or more Central Distribution Units (CDU) feeding multiple Remote Antenna Units (RAU). Figure 1. InCell™ This unit can drive up to 6 RAU’s. Additional CDU’s can be driven using one or more of our Signal Distribution Units (SDU). The required signal distribution is built into the backplane of the chassis minimizing the need for interconnecting cables.

Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide Central Distribution Unit (CDU) The Central Distribution Unit (CDU) is the core module that can drive up to six Remote Antenna Units (RAU. The CDU separates the down and uplink RF signals and converts these to optics for transmission over a 2-core single-mode fiber cable to one of six RAU’s.

The RF connections are Type N. CDU REAR PANEL e View CDU Sid Remote Antenna Unit (RAU) The RAU converts the signal back to RF and provides a single duplex downlink and uplink output port; and the dual band unit combines the two services to a single RF connector.

Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide Indoor Antennas Andrew is developing several new low profile in-building antennas like the examples in Figure 4 and Figure 5. These dual band antennas are based on a product originally designed by our automotive accessory division. We anticipate releasing other antenna products in the next calendar year. Figure 4.

Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide In-Building Implementations Using the Andrew InCell™ System Scalable System Architecture The InCell™ distributed antenna system is a scalable system that can be configured to support up to 384 antenna locations using three building block modules.
Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide The RAU is (shown at Figure 7) weighs only 0.6 pounds and is 38 mm (length) x 127 mm (width) x 165 mm (height). This compact size makes it suitable for close mounting to the antenna. Figure 7.

Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide The Interconnecting Cable Any single mode 2-core fiber cable can be used to drive the RAU a distance of 20Km from the CDU. In this configuration, power to the RAU is supplied from an external 12-28VDC source or an Andrew supplied universal (110/240VAC, 50/60Hz) wall transformer (wall wart). An Andrew manufactured composite cable is also available.
Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide requires system installers to add crimp-on connectors for the copper lines and add SC type connectors to the fiber cables. Refer to Andrew Catalog 38, pages 642-645, for full specifications of the plenum and riser rated cables. Andrew cable assemblies also come with a pulling hook and harness to make the cables easier to install.
Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide The Installation Parameters Installation times will depend on the size of each installation; however, Andrew can provide rough guidelines for installing the CDU and RAU that may be used to determine the total system installation time once the number of equipment parts is determined. The CDU may be mounted in a standard 19” equipment rack or on a wall.

Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide Sample Implementation Figure 12 illustrates a small off-air implementation using an Andrew GridPACK donor antenna, an Andrew Cellular Extender (ACE), and a single InCell™ Central Distribution Unit driving up to six Remote Antenna Units. The donor antenna and extender can be replaced with other RF inputs, such as another off-air interface, a base station, or distribution unit depending on the application.

If the Power indicators for all CDU ports are off, the AC power supply may be bad, AC power may be switched off or there may be another problem with the AC power. The LINK indicator at each CDU port shows that the CDU generated pilot tone was sent over the downlink from the CDU to the RAU then received and transmitted over the uplink path from the RAU back to the CDU.

Andrew InCell™ Fiber Optic Distributed Antenna System Users Guide InCell™ Operation, Maintenance and Support Operation InCell™ system operation is continuous. Andrew recommends using an uninterruptible power supply (UPS) to provide power to the CDU. If the system uses composite cable to provide power to the remote antenna units located throughout the building, the UPS can keep the CDU and all RAUs powered and operational during brownouts and power outages.
